'6G Leadership Race' LG Electronics Transmits Terahertz Band Communication Signal 100m

Successful Wireless Data Transmission Outdoors
Developed with Europe's Largest Applied Science Research Institute Group

[Asia Economy Reporter Minyoung Cha] LG Electronics, which has entered the competition to secure core 6G technologies, succeeded in wirelessly transmitting data over a distance of more than 100 meters outdoors using the 6G terahertz (THz) band.

On the 19th, LG Electronics announced that it transmitted and received communication signals over a straight-line distance of more than 100 meters outdoors using the 6G THz band at the Fraunhofer Heinrich Hertz Institute in Berlin, Germany. Fraunhofer is the largest applied science research group in Europe, with 75 research institutes across Germany.

In this demonstration, LG Electronics developed 'variable beamforming,' which changes the beam direction according to channel variations and receiver location, as well as 'high-gain antenna switching' technology that delivers multiple output signals to antennas, in addition to power amplifiers. Fraunhofer jointly developed a power amplifier that stably outputs communication signals in the 6G THz band.

The newly developed power amplifier raised the output signal to a world-class maximum of 15dBm to enable stable transmission and reception in the frequency range of 155 to 175 gigahertz (GHz). The frequency band for THz wireless transmission technology ranges from 100 GHz to 10 THz. The development of the power amplifier solved the issues of short frequency reach and severe power loss during antenna transmission and reception processes, which are characteristic challenges of 6G ultra-broadband.

6G mobile communication, which will enable transmission speeds of 1 terabit per second (Tbps), is expected to begin standardization discussions around 2025 and be commercialized by 2029. It is essential infrastructure for supporting low-latency, high-reliability communication as well as the all-encompassing intelligent internet of everything (AIoE) connecting people, objects, and spaces.

LG Electronics is also actively engaging in technological collaborations to lead 6G technology. After establishing the ‘LG-KAIST 6G Research Center’ in partnership with the Korea Advanced Institute of Science and Technology (KAIST) in 2019, LG strengthened cooperation with global wireless communication test and measurement equipment manufacturer Keysight earlier this year. In June, LG was also selected as the chair company of the ‘Next G Alliance’ organized by the Alliance for Telecommunications Industry Solutions (ATIS) in the United States.

Park Il-pyung, CTO (Chief Technology Officer) of LG Electronics, emphasized, "With the success of this demonstration, we have taken a step closer to the upcoming 6G era. We will continue to lead global 6G technology development by collaborating with domestic and international research institutions and companies equipped with 6G development capabilities."
